Advice on replacing a vented twin coil cylinder with an unvented one

[noel6072]

Hello folks, I would like your advice on the process of changing my twin coil vented cylinder with an unvented cylinder. I have very strong mains pressure, but my hot and cold bathroom water pressure is very low and is gravity fed with a water tank in the attic and my bath would take too long to fill. I would like to make some space in the loft for a future conversion by possibly having no water tank in the loft if an unvented system was installed.

I have two heat sources, I have an outdoor grant vortex condenser oil boiler, and also a solid fuel stove with back boiler so require a twin coil cylinder. I have a budget so would like a rough cost of an unvented cylinder. Many thanks in advance.

Sadly you wont be able to use an unvented with the solid fuel stove.
there are ways but would be outside your budget 🙂

your installer will consult with you about this as you need the g3 qualification to install an unvented cylinder.
tis illegal to install yourself 🙂

You could have the back boiler disconnected, but im guessing you will want to keep it.

Like utilising the old cylinder and buying a pump :wink:

This is why you should get a pro on board. Google doesn't usually tell you that your actions could blow the house up or kill half the family which solid fuel on an unvented could.
